Description

  The present invention relates to a floor for restricting runout in the thickness direction during travel of the hanging door body by being inserted into a traveling groove having a cross-sectionally open cross-section formed along the lower end surface of the hanging door body. The present invention relates to a guide for a hanging door installed on a surface.

  Conventionally, a suspension door is known in which a suspension door body is suspended and held on a rail attached to an entrance frame of the entrance / exit frame, and the suspension door is supported only at the upper end during traveling. In order to prevent this from swinging in the front-rear direction (when opening and closing), a guide that is attached to the suspension door body is installed on the floor surface.

  And, as a guide for the sliding door, a type that is fitted into a traveling groove having a U-shaped cross section opened downwardly formed along the lower end surface of the hanging door body is known. For example, a guide pin is provided with a magnet. In Japanese Patent Laid-Open No. 8-326402, a guide roller having a roller supported on the vertical axis is erected on a substrate so as to be movable in the thickness direction of the suspension door body. Presented.

  However, when the guide pin and the guide plate provided in the above publication are provided, considering the friction between the suspension door main body and the guide, if the two are arranged in close contact with each other, it becomes difficult to run the suspension door main body and it becomes difficult to open and close. It is necessary to form a certain gap between the two and rattling cannot be eliminated. In the case of guide pins, a plurality of guide pins need to be arranged on the floor surface at regular intervals, and a smooth floor surface cannot be obtained, and the suspension door body and the guide pin are in direct contact with each other. Therefore, for example, when an impact is applied to the suspension door main body, there is a problem that it is damaged.

In addition, a guide roller that is supported by a roller on the vertical axis shown in the above publication is installed on the substrate so as to be movable in the thickness direction of the hanging door body. The guide roller is suspended by moving the guide roller in the thickness direction. It is possible to run with the guide roller in contact with the guide groove of the door, but since the movement is limited to either the front or the rear, for example, it is used for a closed part of a hanging door having a sealing function In some cases, it is convenient, but it is difficult to move the suspension door body along the central axis extending in the traveling direction.

  The present invention has been made in view of the above circumstances, and it is possible not only to move the suspension door main body along the central axis in the thickness direction, but also to obtain a flat floor surface that is easy to install and adjust. Therefore, the present invention provides a guide for a suspension door that is economically superior in that it can absorb an impact applied to the suspension door and can be applied to a conventional guide pin.

  The guide of the hanging door according to the present invention made to achieve the above object is inserted into a U-shaped traveling groove opened downward and formed along the lower end surface of the hanging door body. A guide for a suspension door installed on the floor surface in order to regulate the deflection in the thickness direction during traveling, a substrate disposed on the floor surface, a pair of guide rollers erected on the substrate, The board includes a mounting screw for mounting the board to the floor surface, and the board has a circular shaft hole into which the shaft portion of the mounting screw can be inserted at least at the center position in the width direction (thickness direction of the hanging door). In addition, the pair of guide rollers are erected at predetermined positions that are symmetrical in the width direction (thickness direction of the hanging door) and the length direction (traveling direction of the hanging door) across the shaft hole. It is characterized by.

  By rotating the substrate placed on the floor surface in the shaft hole arranged at the center position in the thickness direction, the pair of guide rollers are placed on the inner side surfaces before and after the guide groove formed along the lower end surface of the suspension door body. By making each contact, the suspension door body is allowed to travel without rattling along the center position in the thickness direction.

  Further, in the present invention, at least one of the mounting screw holes formed at the end portion in the running direction of the substrate in order to fix the substrate to the floor surface has an arc shape positioned on the circumference centering on the shaft hole. In this case, the inner surface of the front and rear of the guide groove formed along the lower end surface of the suspension door by rotating the substrate while the set screw passes through the set screw hole and is temporarily fixed to the floor surface The substrate can be easily placed on the floor surface at a predetermined rotational position.

  Further, in the present invention, when a floor surface mounting plate that supports the substrate so as to be rotatable about the support shaft and can be fixed at a desired rotational position is attached to the lower surface of the substrate, further adjustment is possible. In addition to being easy, for example, the floor mounting plate can be provided with a mounting portion movable in the front-rear direction (thickness direction of the hanging door).

  As mentioned above, according to this invention, a suspension door main body can be reliably and smoothly run along the center position of the thickness direction of a suspension door main body. In addition, it is easy to install and adjust, so that many guide pins do not protrude from the floor as in the case of conventional guide pins, and it is easy to manufacture, can be provided at low cost, and is economical. Are better.

  Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

  1 to 3 show a preferred embodiment of the present invention, and the guide 1 of the suspension door according to the present invention has a predetermined width (for example, the width of a guide groove formed on the lower surface of the suspension door to be used). The metal substrate 1 having a substantially horizontally long rectangular shape having an appropriate length and thickness, a pair of guide rollers guide rollers 3a and 3b erected on the substrate 2, and the substrate 2 are installed on the floor surface. Mounting screws 71, 72, and 73.

  More specifically, the substrate 2 is formed with a circular shaft hole 21 that can be inserted through the shaft portion 71a of the mounting screw 71 at the center position, and is symmetrical in the length direction and the width direction across the shaft hole 21. The guide rollers 3a and 3b are erected so as to face each other at a predetermined position.

  The guide rollers 3a and 3b are well known in the art, and a roller body 32 made of hard synthetic resin having functionality is rotatably supported on a metal vertical axis 31 implanted in the substrate 2. Yes, if necessary, a lubricating member (not shown) such as a bearing may be provided. At both ends in the length direction of the substrate 2, mounting screw holes 22, 23 formed in an arc shape located on a predetermined circumference centering on the shaft hole 21 are formed.

  As shown in FIG. 4, this embodiment configured as described above is attached to the floor surface 6 positioned at the lower end portion on the pull-in side of the suspension door body 5 suspended from the rail 41 attached to the Kamoi 4, for example. Used.

  FIGS. 5 and 6 show an attachment state and an adjustment state. First, as shown in FIG. 5, the shaft hole 21 is located at a predetermined position of the central axis C along the center in the traveling direction of the suspension door body 5 on the floor surface 6. For example, as shown in the figure, the guide roller 3a on the base end side is disposed at a position where it abuts on the inner side surface 51c on the drawing side of the guide groove 51 formed along the lower end of the suspension door body 5, and the shaft hole 21 And the attachment screws 71, 72, and 73 are inserted into the attachment screw holes 22 and 23, respectively, and temporarily fixed to the floor surface 6.

  Next, as shown in FIG. 6, the substrate 2 is rotated in the horizontal direction around the support shaft that is the mounting screw 61, and the roller main body 32 of the guide roller 3 a on the proximal end side, for example, is on the front side of the guide groove 51. The roller main body 32 of the guide roller 3b on the front end side is brought into contact with the inner side surface 51b on the front side of the guide groove 51, respectively.

  At this time, the guide rollers 3a and 3b only have to guide the suspension door body 5, and when pressed, the contact resistance increases and affects the traveling of the suspension door body 5, so care must be taken.

  When the predetermined rotational position of the substrate is determined, the mounting screws 71, 72, 73 are screwed to fix the substrate 2 to the floor surface 6.

  In this way, according to the guide 1 according to the present embodiment installed on the floor surface 6, the roller body 32 of the guide roller 3 a on the proximal end side is placed on the inner side surface 51 a on the front side of the guide groove 51, and the guide on the distal end side. Since the roller body 32 of the roller 3b is in contact with the inner side surface 51b on the front side of the guide groove 51, the suspension door body 5 swings in the A direction indicated by the arrow as shown in FIG. Absent. Further, since the guide roller 3b on the front end side is in contact with the inner side surface 51b on the front side of the guide groove 51, it swings, but the suspension door body 5 is basically a linear rail as shown in FIG. Since the movement is restricted by 41, both the guide rollers 3a and 3b serve as guides, so there is no fear of swinging in the thickness direction. Further, in this embodiment, since the guide rollers 3a and 3b and the suspension door body 5 are not forcibly in contact with each other, for example, even if an impact is applied to the suspension door body 5, the suspension door body 5 is moved by the guide 1. There is no worry about damage.

  In the present embodiment, the front guide roller 3a is disposed on the retracting side of the suspension door 5. However, the present invention is not limited to this, and the positions of the guide rollers 3a and 3b may be reversed. In this embodiment, the mounting screws 71, 72, 73 are all screwed to the floor surface 6, but at least one of them serves as a fulcrum for the floor surface 6. It does not have to be screwed.

  7 and 8 show different embodiments of the present invention, and the configuration of the substrate 2 and the guide rollers 3a and 3b is substantially the same as that of the above-described embodiment. The floor mounting plate 8 is attached to the support shaft 24 that is inserted and supported in the shaft hole 21 so as to be rotatable about the support shaft 24.

  In particular, in the present embodiment, one arcuate mounting screw hole 22 centering on the shaft hole 21 is formed in the substrate 2, and a short length is formed in the screw hole 81 formed on the floor surface mounting plate 8 positioned below the mounting hole. The set screw 74 is screwed, and the rotation adjustment is possible with one set screw 74. Further, screw holes 82 and 83 extending in the width direction are formed at both ends in the traveling direction of the floor mounting plate 8. The mounting screws 75 and 76 can be attached to the floor surface 6 so as to be movable in the thickness direction (front-rear direction).

  FIG. 9 shows an example in which the present invention is applied to a conventional example using a conventional guide pin type guide roller, and the conventional hanging door 5 is used only by changing the guide 1 in this way. Can also be implemented.
